Angiomyolipomas are rare mesenchymal tumours consisting of smooth muscle, blood vessels and adipocytes in variable proportions. These tumours are more usually seen in kidneys (incidence 0.3-3%), and the extrarenal location is rare. Since its initial description by Ishak in 1976, only about 200 cases of hepatic angiomyolipomas have been reported. ...

We evaluated the outcome and etiologies of small renal masses (less than 1 cm in size) discovered incidentally on 2 consecutive CTs that investigated nonurologic abdominal complaints. A retrospective search for incidentally discovered small renal masses, less then 1 cm in size, was carried out in the files of 6 ...

There are several well-described causes of a painful mass following total hip arthroplasty including polyethylene and metal wear debris, infection, expanding hematoma, dislocation, and synovial cysts. In addition to causing pain, these lesions, when large enough, may cause neurologic and vascular compromise. Rapid growth of the mass may clinically and ...

The localized expansion of cortical plates is observed. Radiographically, it consists of well-defined radiopacity with a radiolucent band. Here is a case report of ...

Ganglioneuromas are benign tumors of the sympathetic nervous system that rarely arise in the adrenal gland. Majority of cases are detected incidentally since they are usually asymptomatic. Up to the current era of laparoscopic adrenal mass excision, this unusual entity has not been adequately reported in the surgical literature. A ...

Oral melanoma (OM) is a rare, malignant neoplasm of melanocytic origin. It accounts for 0.2 - 8% of all melanomas. In contrast to its cutaneous counterpart, OM has poor prognosis, possibly due to late clinical diagnosis, nonexistence of standardized clinical or histopathological grading and anatomical limitation in complete excision of ...

We present a rare case of a cystic posterior pharyngeal wall mass in a 5 year old child in whom prior surgery without biopsy led to considerable delay in both diagnosis and definitive treatment.

A testicular mass in an elderly man has a high probability of being a lymphoma. However, when the pathologist is faced with a neoplastic lymphoid infiltrate in the testes, one rarely considers Hodgkin's lymphoma as a possibility, as a vast majority turn out to be diffuse large B cell lymphomas. ...

Endometriosis is a pathological feature induced by the presence and ectopic development of islets of endometrial active cells. The most common site of occurrence is the genital system, causing specific gynecological pathology. The extragenital localization of endometriosis is rare, but it is more severe and it may have a malignant ...

Synovial sarcomas commonly occur in the extremities of young adults. A primary occurrence in the mediastinum is very rare with only a few reported cases in the world literature.
